Domestic & Overseas Sourcing

Great design is only the beginning. The real magic happens when GMPC transforms that perfect two dimensional concept into a living, three dimensional product.

The key to our development success is our detail-oriented, highly experienced, product specialists. Our developers are trained in domestic and overseas production and approach every project equipped with countless years of individual and institutional knowledge.

GMPC’s development teams located in each of our domestic and international locations regularly share knowledge both organically as well as through our proprietary development software that enables GMPC to leverage over 40 years of product development experience and wisdom.

Best in Class

GMPC has manufactured and imported products from Asia for over 40 years. Over this period of time we have cultivated and maintained long-term partnerships with hand-selected, best in class factories in each of our product categories.

GMPC exclusively partners with factories who share our commitment not only to manufacturing the finest quality products but to do so while providing their employees with a safe and healthy work environment. GMPC recognizes, understands and remains fully committed to partnering with factories that meet or exceed our customers’ most stringent compliance requirements. To this end, our factories are regularly inspected and audited by both our in-house compliance experts as well as third party auditors to assure that each factory meets wage, child labor, overtime, health, safety, and environmental Standards.

We take responsibility

QA and QC are the final pieces of the product development lifecycle. GMPC defines success not as designing a great item or even making great proto samples, but rather as delivering our customers production goods that exceed their expectations.

Quality Assurance is managed by GMPC’s internal team of inspectors located throughout China. GMPC’s quality control protocol includes both in-line and post production inspections performed at the factory level. We also regularly inspect the raw materials and components to assure that they are of acceptable quality prior to the start of production.

Our philosophy is to invest heavily in resources that enable us to avoid quality issues from the start rather than address them after the fact. Should an issue arise, our customers take solace knowing that GMPC is a US based company with an impeccable reputation. We are proud to have a proven record of taking responsibility and honor all of our commitments.

Supply Chain Solutions

Production is completed, now what? The sheer volume of goods GMPC annually imports, assures our customers efficient customs clearance and the most reliable, economical international and domestic freight pricing.

Utilizing state-of-the-art technology, GMPC tracks and coordinates every shipment from the time it leaves our overseas factories until it reaches its final destination. Our team handles all documentation for timely customs clearance and arranges ocean and air freight from Asia to the U.S. and other worldwide destinations.

Our Story

Our story begins in Los Angeles in 1974.

GMPC’s founder, Gary Mandel, a creative and ambitious, product-centric perfectionist wanted more for his customers than existing design and manufacturing resources permitted.  Gary was determined to provide the highest quality, bespoke products and accessories, capable of complementing and enhancing his customers’ brands.  He was committed to the notion that every item created by GMPC should both embody and enrich the brand that it is connected to.

Gary quickly recognized that the key to achieving his vision was building a world class design team, deep product expertise and international manufacturing capabilities….
